l 1 l l "In u gva/vanto@ Patented June 23, 1931 ALMIRA L. I-I. WILLSON,0F VIRDEN, ,ILLINOIS oLosURE FASTENER- Application filed September 14,1929. Serial No. 392,702.

This invention relates to a closure fastenerl and the invention has foran object to provide a device of this kind particularly intended for usewith lids of safe deposit'boxes i using a plurality of lids andwhereinall ofv the lids are effectively locked in closed position undercontrol of a single lid.

It is also an object of the invention to provideV a closurefastener foruse in connection with a .box having a plurality of lids wherein one ofthe lids is adapted to be held in closed position by a lock mechanismoperable from without and wherein the remainder of said lids are lockedin such closed position when the first named lid is closed.

The invention consists in the details of construction and in thecombination and arrangement `of the several parts of my improved closurefastener whereby certain iniportant advantages are attained and thedevice rendered simpler, less expensive and otherwise more convenientand advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, whereinz Figure l is a fragmentary longitudinal sectional viewtaken through a safe deposit boX having applied thereto a closurefastener for the lids constructed in accordance with an embodimentV ofmy invention, thesecond position of one of the lids beingdiagrammatically indicated by brok-en lines;

Figure 2 is a sectional view taken substantially on the line 2-*2 ofFigure l looking in the direction of the arrow;

Figure 3 is a fragmentary sectional view taken substantially on the line3-3 of Figure l looking in the direction of the arrow.

In the accompanying drawings, S denotes a safe deposit boXof aconventional type and which has associated with its top a pair of hingedlids A and B, said lids A and B having swinging movement in the samegeneral direction. The lid A is pivotally connected at its inner endportion with a rod 1 extending transversely of the boX at substantiallyits longitudinal center while the lid B has an end portionin closeengagement with a second rod 2 positioned immediately adjacent to an endwall 3 of the box S. By this mounting of the lids A and B they both haveswinging movement in the same general direction into either open `orclosed position,

`and when in closed position said lids A and its free end portionclosely approa-ches'the hinged end rofthe lid A and saidfree end portionof the lid B is provided with a depend-V ing flange 5 disposedtransversely thereof, said flange having longitudinally spaced lslots 6.rIhis slotted flange 5 serves as a keeper for coaction with the lugs 7carried by the inner or hinged end portion of the lid A. These lugs 7are inwardly offset with respect to the lid A and extend beyond'thehinged end portion of said lid A and `extend sufficient to pass throughthe slots 6 of the flange 5 when the lid A is fully closed, the slots 6being of sunlicient width to permit such entry. By this means with thelid B first fully closed, the lid A when closed provides effective meansthrough the medium of the lugs. 7 and the flange 5 to hold the lid Bagainst opening movement until after the lid A has been raised.

When desired to have accesswithin the boX S it is only necessary tooperate the mechanism I to release the lid A and as the lid A is Yraised the lugs 7 are freed from the flange 5 of the lid B whereupon thelid B if desired can also be lifted into open position. In closing theboX the lid B is first moved into closed position and as the lid A isswung into closed position the lugs 7 will engage through the slots 6 ofthe flange 5 and thereby effectively hold the lid B against liftingmovement until after the lid A has been again raised.

From the foregoing description it is thought to be obvious that aclosure fastener constructed in accordance With my invention isparticularly Well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification Without departing from the principles and spirit thereofand for this reason I do not Wish to be understood as limiting myself tothe precise arrangement and formation of the several parts herein shownin'carrying out my invention in practice except as hereinafter claimed.

l. In combination, a pair of abutting hinged closure members, a keepercarried by one of said members, and a tongue carried by the other memberand engageable in said keeper whereby to lock said one member uponclosing of said other member.

2. In combination, a pair of alined hinged closure members, the free endof one member abutting the hinged end of the other member, a keepercarried by said one member adjacent the free end thereof, and a lockingtongue carried by the other member adjacent the hinged end, said tonguewhen both members are in closed position engaging said keeper whereby tolock said one member.

In testimony whereof I hereunto aHiX my signature.

ALMIRA L. H. WILLSON.
